+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement
+(CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an
+    [individual CLA](https://developers.google.com/open-source/cla/individual).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a
+    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the
+   [issue tracker](https://github.com/google/googletest).
+1. Please don't mix more than one logical change per submittal,
+   because it makes the history hard to follow. If you want to make a
+   change that doesn't have a corresponding issue in the issue
+   tracker, please create one.
+1. Also, coordinate with team members that are listed on the issue in
+   question. This ensures that work isn't being duplicated and
+   communicating your plan early also generally leads to better
+   patches.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.
+
+If you are a Googler, it is preferable to first create an internal change and
+have it reviewed and submitted, and then create an upstreaming pull
+request here. 
+
+## The Google Test and Google Mock Communities ##
+
+The Google Test community exists primarily through the
+[discussion group](http://groups.google.com/group/googletestframework)
+and the GitHub repository.
+Likewise, the Google Mock community exists primarily through their own
+[discussion group](http://groups.google.com/group/googlemock).
+You are definitely encouraged to contribute to the
+discussion and you can also help us to keep the effectiveness of the
+group high by following and promoting the guidelines listed here.
+
+### Please Be Friendly ###
+
+Showing courtesy and respect to others is a vital part of the Google
+culture, and we strongly encourage everyone participating in Google
+Test development to join us in accepting nothing less. Of course,
+being courteous is not the same as failing to constructively disagree
+with each other, but it does mean that we should be respectful of each
+other when enumerating the 42 technical reasons that a particular
+proposal may not be the best choice. There's never a reason to be
+antagonistic or dismissive toward anyone who is sincerely trying to
+contribute to a discussion.
+
+Sure, C++ testing is serious business and all that, but it's also
+a lot of fun. Let's keep it that way. Let's strive to be one of the
+friendliest communities in all of open source.
+
+As always, discuss Google Test in the official GoogleTest discussion group.
+You don't have to actually submit code in order to sign up. Your participation
+itself is a valuable contribution.
+
+## Style
+
+To keep the source consistent, readable, diffable and easy to merge,
+we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project.  All patches will be expected
+to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
+
+## Requirements for Contributors ###
+
+If you plan to contribute a patch, you need to build Google Test,
+Google Mock, and their own tests from a git checkout, which has
+further requirements:
+
+  * [Python](https://www.python.org/) v2.3 or newer (for running some of
+    the tests and re-generating certain source files from templates)
+  * [CMake](https://cmake.org/) v2.6.4 or newer
+  * [GNU Build System](https://en.wikipedia.org/wiki/GNU_Build_System)
+    including automake (>= 1.9), autoconf (>= 2.59), and
+    libtool / libtoolize.
+
+## Developing Google Test ##
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+    mkdir mybuild
+    cd mybuild
+    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python.  If the cmake command complains about not being
+able to find Python (`Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
+executable can be found:
+
+    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests.  On \*nix,
+this is usually done by 'make'.  To run the tests, do
+
+    make test
+
+All tests should pass.
+
+### Regenerating Source Files ##
+
+Some of Google Test's source files are generated from templates (not
+in the C++ sense) using a script.
+For example, the
+file include/gtest/internal/gtest-type-util.h.pump is used to generate
+gtest-type-util.h in the same directory.
+
+You don't need to worry about regenerating the source files
+unless you need to modify them.  You would then modify the
+corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
+generator script.  See the [Pump Manual](googletest/docs/PumpManual.md).
+
+## Developing Google Mock ###
+
+This section discusses how to make your own changes to Google Mock.
+
+#### Testing Google Mock Itself ####
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you'll need Autotools.  First, make sure you have followed
+the instructions above to configure Google Mock.
+Then, create a build output directory and enter it.  Next,
+
+    ${GMOCK_DIR}/configure  # try --help for more info
+
+Once you have successfully configured Google Mock, the build steps are
+standard for GNU-style OSS packages.
+
+    make        # Standard makefile following GNU conventions
+    make check  # Builds and runs all tests - all should pass.
+
+Note that when building your project against Google Mock, you are building
+against Google Test as well.  There is no need to configure Google Test
+separately.

-### Developing Google Mock ###
-
-This section discusses how to make your own changes to Google Mock.
-
-#### Testing Google Mock Itself ####
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you'll need Autotools.  First, make sure you have followed
-the instructions above to configure Google Mock.
-Then, create a build output directory and enter it.  Next,
-
-    ${GMOCK_DIR}/configure  # try --help for more info
-
-Once you have successfully configured Google Mock, the build steps are
-standard for GNU-style OSS packages.
-
-    make        # Standard makefile following GNU conventions
-    make check  # Builds and runs all tests - all should pass.
-
-Note that when building your project against Google Mock, you are building
-against Google Test as well.  There is no need to configure Google Test
-separately.
-
-#### Contributing a Patch ####
-
-We welcome patches.
-Please read the [Developer's Guide](docs/DevGuide.md)
-for how you can contribute. In particular, make sure you have signed
-the Contributor License Agreement, or we won't be able to accept the
-patch.
-
 Happy testing!

-If you are interested in understanding the internals of Google Mock,
-building from source, or contributing ideas or modifications to the
-project, then this document is for you.
-
-# Introduction #
-
-First, let's give you some background of the project.
-
-## Licensing ##
-
-All Google Mock source and pre-built packages are provided under the [New BSD License](http://www.opensource.org/licenses/bsd-license.php).
-
-## The Google Mock Community ##
-
-The Google Mock community exists primarily through the [discussion group](http://groups.google.com/group/googlemock), the
-[issue tracker](https://github.com/google/googletest/issues) and, to a lesser extent, the [source control repository](../). You are definitely encouraged to contribute to the
-discussion and you can also help us to keep the effectiveness of the
-group high by following and promoting the guidelines listed here.
-
-### Please Be Friendly ###
-
-Showing courtesy and respect to others is a vital part of the Google
-culture, and we strongly encourage everyone participating in Google
-Mock development to join us in accepting nothing less. Of course,
-being courteous is not the same as failing to constructively disagree
-with each other, but it does mean that we should be respectful of each
-other when enumerating the 42 technical reasons that a particular
-proposal may not be the best choice. There's never a reason to be
-antagonistic or dismissive toward anyone who is sincerely trying to
-contribute to a discussion.
-
-Sure, C++ testing is serious business and all that, but it's also
-a lot of fun. Let's keep it that way. Let's strive to be one of the
-friendliest communities in all of open source.
-
-### Where to Discuss Google Mock ###
-
-As always, discuss Google Mock in the official [Google C++ Mocking Framework discussion group](http://groups.google.com/group/googlemock).  You don't have to actually submit
-code in order to sign up. Your participation itself is a valuable
-contribution.
-
-# Working with the Code #
-
-If you want to get your hands dirty with the code inside Google Mock,
-this is the section for you.
-
-## Checking Out the Source from Subversion ##
-
-Checking out the Google Mock source is most useful if you plan to
-tweak it yourself.  You check out the source for Google Mock using a
-[Subversion](http://subversion.tigris.org/) client as you would for any
-other project hosted on Google Code.  Please see the instruction on
-the [source code access page](../) for how to do it.
-
-## Compiling from Source ##
-
-Once you check out the code, you can find instructions on how to
-compile it in the [README](../README.md) file.
-
-## Testing ##
-
-A mocking framework is of no good if itself is not thoroughly tested.
-Tests should be written for any new code, and changes should be
-verified to not break existing tests before they are submitted for
-review. To perform the tests, follow the instructions in [README](../README.md) and
-verify that there are no failures.
-
-# Contributing Code #
-
-We are excited that Google Mock is now open source, and hope to get
-great patches from the community. Before you fire up your favorite IDE
-and begin hammering away at that new feature, though, please take the
-time to read this section and understand the process. While it seems
-rigorous, we want to keep a high standard of quality in the code
-base.
-
-## Contributor License Agreements ##
-
-You must sign a Contributor License Agreement (CLA) before we can
-accept any code.  The CLA protects you and us.
-
-  * If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an [individual CLA](http://code.google.com/legal/individual-cla-v1.0.html).
-  * If you work for a company that wants to allow you to contribute your work to Google Mock, then you'll need to sign a [corporate CLA](http://code.google.com/legal/corporate-cla-v1.0.html).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it.
-
-## Coding Style ##
-
-To keep the source consistent, readable, diffable and easy to merge,
-we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project.  All patches will be expected
-to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
-
-## Submitting Patches ##
-
-Please do submit code. Here's what you need to do:
-
-  1. Normally you should make your change against the SVN trunk instead of a branch or a tag, as the latter two are for release control and should be treated mostly as read-only.
-  1. Decide which code you want to submit. A submission should be a set of changes that addresses one issue in the [Google Mock issue tracker](https://github.com/google/googletest/issues). Please don't mix more than one logical change per submittal, because it makes the history hard to follow. If you want to make a change that doesn't have a corresponding issue in the issue tracker, please create one.
-  1. Also, coordinate with team members that are listed on the issue in question. This ensures that work isn't being duplicated and communicating your plan early also generally leads to better patches.
-  1. Ensure that your code adheres to the [Google Mock source code style](#Coding_Style.md).
-  1. Ensure that there are unit tests for your code.
-  1. Sign a Contributor License Agreement.
-  1. Create a patch file using `svn diff`.
-  1. We use [Rietveld](http://codereview.appspot.com/) to do web-based code reviews.  You can read about the tool [here](https://github.com/rietveld-codereview/rietveld/wiki).  When you are ready, upload your patch via Rietveld and notify `googlemock@googlegroups.com` to review it.  There are several ways to upload the patch.  We recommend using the [upload\_gmock.py](../scripts/upload_gmock.py) script, which you can find in the `scripts/` folder in the SVN trunk.
-
-## Google Mock Committers ##
-
-The current members of the Google Mock engineering team are the only
-committers at present. In the great tradition of eating one's own
-dogfood, we will be requiring each new Google Mock engineering team
-member to earn the right to become a committer by following the
-procedures in this document, writing consistently great code, and
-demonstrating repeatedly that he or she truly gets the zen of Google
-Mock.
-
-# Release Process #
-
-We follow the typical release process for Subversion-based projects:
-
-  1. A release branch named `release-X.Y` is created.
-  1. Bugs are fixed and features are added in trunk; those individual patches are merged into the release branch until it's stable.
-  1. An individual point release (the `Z` in `X.Y.Z`) is made by creating a tag from the branch.
-  1. Repeat steps 2 and 3 throughout one release cycle (as determined by features or time).
-  1. Go back to step 1 to create another release branch and so on.

-## Developing Google Test ##
-
-This section discusses how to make your own changes to Google Test.
-
-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python (`Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
-executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On \*nix,
-this is usually done by 'make'.  To run the tests, do
-
-    make test
-
-All tests should pass.
-
-Normally you don't need to worry about regenerating the source files,
-unless you need to modify them.  In that case, you should modify the
-corresponding .pump files instead and run the pump.py Python script to
-regenerate them.  You can find pump.py in the [scripts/](scripts/) directory.
-Read the [Pump manual](docs/PumpManual.md) for how to use it.
